DescriptionThe THS4531AIDGK device is a low-power, fully differential amplifier with input common-moderange below the negative rail and rail-to-rail output. The device is designed for low-power dataacquisition systems and high-density applications where power consumption and dissipation iscritical.
The device features accurate output common-mode control that allows for DC coupling whendriving analog-to-digital converters (ADCs). This control, coupled with the input common-mode rangebelow the negative rail and rail-to-rail output, allows for easy interface from single-endedground-referenced signal sources to successive-approximation registers (SARs), and delta-sigma (ΔΣ)ADCs using only single-supply 2.5-V to 5-V power. The THS4531AIDGK is also a valuable tool forgeneral-purpose, low-power differential signal conditioning applications.
